iOS Swift－全局右滑返回

1、设置自定义的右滑手势，别忘记禁止系统右滑手势

let target = self.interactivePopGestureRecognizer?.delegate
        let pan:UIPanGestureRecognizer = UIPanGestureRecognizer.init(target: target!, action: Selector(("handleNavigationTransition:")))
        self.view.addGestureRecognizer(pan)

        self.interactivePopGestureRecognizer?.isEnabled = false
        pan.delegate = self

2、UIGestureRecognizerDelegate代理方法筛选手势作用条件

设置根控制器右滑手势不起作用，如果不设置，一旦在根控制器中右滑，将造成app卡死

    func gestureRecognizerShouldBegin(_ gestureRecognizer: UIGestureRecognizer) -> Bool {
        return self.childViewControllers.count > 1
    }

这样即可
